Given the relevant role of social capital for many real-life dimensions such as health, well-being, democracy, and economic growth, it is particularly relevant to monitor its changes over time and across countries. This is particularly urgent in the light of previous empirical evidence and the theoretical expectation that civil society erodes. Previous literature focused mainly on the case of US, devoting less attention to what happened in other regions of the world, such as Europe. We contribute to this literature providing the first encompassing account of how the trends of 10 proxies of social capital have changed in 30 Western and Eastern European countries between years 1990 and 2008/09. To this aim we adopt the WVS/EVS integrated data-set.
